Il primo ora con la tua VPS: guida completa da macchina nuda a server sicuro e pronto (per rendere più sicuro il tuo OpenClaw)

Un VPS appena acquistato è come una porta senza serratura, con script kiddie di tutto il mondo che bussano alla porta. Questo articolo ti guida a mettere una bella serratura. Così il tuo “gamberetto” (openclaw) non se ne va in giro a combinare guai. 0. Prima di iniziare Hai appena preso un VPS, tutto gasato con IP e password di root in mano, e poi? L’approccio di molti è: partire subito a installare roba e deployare progetti. È un’abitudine pericolosa. Il tuo VPS ha un IP pubblico, il che s...

VPS 到手后的第一个小时：从裸机到安全可用的完整初始化指南（让你的OpenClaw更安全）

新买的 VPS 就像一扇没上锁的门，全世界的脚本小子都在敲。这篇文章带你把门锁好。让你的小龙虾（openclaw）不会乱跑乱动。 0、写在前面刚买了一台 VPS，兴冲冲地拿到 IP 和 root 密码，然后呢？很多人的做法是：直接开始装软件、部署项目。这是个危险的习惯。你的 VPS 有一个公网 IP，意味着全世界任何人都可以尝试连接它。而默认配置下：端口是公开的 22 用户名是众所周知的 root 只剩一个密码在保护你每天有无数自动化脚本在扫描 IP 段，尝试用常见密码暴力破解。你的服务器从上线那一刻起，就已经在被攻击了。所以，拿到 VPS 后的第一件事，不是装软件，而是做安全初始化。 1、期望目标这篇文章的目标是： ✅ 建立安全的远程访问：SSH 密钥登录 + 非默认端口 ✅ 创建普通用户：避免直接使用 root ✅ 配置防火墙：只开放必要端口 ✅ 启用网络加速：BBR 让网络起飞 ✅ 防止暴力破解：fail2ban 自动封禁恶意 IP 做完这些，你的 VPS 就有了一个坚实的基础，可以安心部署各种服务了。 2、计划思考为什么要做这些配置？刚...

VPS 개통 후 첫 1시간: 아무것도 없는 상태에서 안전하게 쓸 수 있게 세팅하는 완전 초기화 가이드 (너의 OpenClaw 더 안전하게 만들기)

새로 산 VPS는 자물쇠 없는 현관문이나 다름없어요. 전 세계의 스크립트 키디들이 끊임없이 문을 두드리고 있죠. 이 글에서는 그 문을 확실히 잠그는 방법을 알려드릴게요. 여러분의 openclaw가 함부로 밖으로 나돌아다니지 않도록 말이에요. 0. 들어가며 VPS 한 대를 새로 샀고, 신나서 IP와 root 비밀번호를 받았다면 그다음은 뭘까요? 많은 분들이 이렇게 하시더라고요: 곧바로 소프트웨어 설치하고 프로젝트 배포를 시작해버리죠. 이건 아주 위험한 습관이에요. 여러분의 VPS에는 공인 IP가 달려 있습니다. 즉, 전 세계 누구나 접속을 시도해볼 수 있다는 뜻이죠. 게다가 기본 설정 상태에서는: 포트는 22로 탁 트여 있고 사용자 이름은 누구나 아는 root이며 남은 건 비밀번호 하나뿐입니다 매일 수많은 자동화 스크립트가 IP 대역을 스캔하면서 흔한 비밀번호로 무차별 대입 공격을 시도합니다. 서버가 온라인에 올라가는 순간부터 이미 공격받고 있는 거예요. 그러니까 VPS를...

Pierwsza godzina z nowym VPS: kompletny przewodnik po inicjalizacji od gołej maszyny po bezpieczny i gotowy do pracy serwer (niech Twój OpenClaw będzie bezpieczniejszy)

Świeżo kupiony VPS jest jak otwarte na oścież drzwi, w które puka cała armia skrypt-kiddies z całego świata. W tym artykule pokażę Ci, jak założyć solidną kłódkę. Żeby Twój “rak” (openclaw) nie włóczył się, gdzie popadnie. 0. Słowo wstępu Kupiłeś właśnie VPS-a, z radością wpisujesz IP i hasło roota, a potem? Większość ludzi robi tak: od razu rzuca się do instalacji softu i deployu projektu. To fatalny nawyk. Twój VPS ma publiczny IP, co oznacza, że dosłownie każdy na świecie może spróbować ...

VPS मिलते ही पहला घंटा: नंगे सर्वर से सुरक्षित और इस्तेमाल-लायक बनने तक का पूरा इनिशियलाइज़ेशन गाइड (अपने OpenClaw को और सुरक्षित बनाओ)
